The present invention discloses an encapsulation composition, an encapsulation film including the encapsulation composition, and an electronic device module. The encapsulation composition includes a polymer matrix, a tackifier and a free radical initiator. Based on 100 parts by weight of the polymer matrix, the polymer matrix includes 5 to 100 parts by weight of highly branched polyethylene (P1), 0 to 95 parts by weight of an ethylene--olefin copolymer, and 0 to 70 parts by weight of an ethylene-polar monomer copolymer. The highly branched polyethylene (P1) is an ethylene homopolymer having a branch structure and has a degree of branching of not less than 40 branches/1,000 carbon atoms. A density of the ethylene--olefin copolymer is not higher than 0.91 g/cm.sup.3. The encapsulation composition provided by the present invention has good volume resistivity, aging resistance, processability and low cost.

The present invention pertains to a fluoropolymer hybrid organic/inorganic composite, to a film comprising said fluoropolymer hybrid organic/inorganic composite and to uses of said film in various applications, especially in electrochemical and in photo-electrochemical applications.

The present invention relates to an encapsulant capable of reducing potential-induced degradation (PID). The encapsulant is used to seal a solar cell to form a photovoltaic module, in which silica gel is dispersed in the encapsulant as a sodium ion adsorbent. Since the silica gel that is highly transparent is used as the sodium ion adsorbent, it is possible to prevent PID attributable to sodium ions and to prevent deterioration in photovoltaic efficiency of the photovoltaic module. Since the silica gel has a high specific surface area, it is possible to adsorb sodium ions with a small amount of the silica gel.
